Switching Waveforms
Notes
Document Number: 38-05289 Rev. *M
28. For this waveform ZZ is tied LOW.
29. When CE is LOW, CE
30. The IGNORE CLOCK EDGE or STALL cycle (Clock 3) illustrated CEN being used to create a pause. A write is not performed during this cycle.
31. Device must be deselected when entering ZZ mode. See cycle description table for all possible signal conditions to deselect the device.
32. I/Os are in high Z when exiting ZZ sleep mode.
